Improved Fuzzy C-Means Clustering for Transformer Fault Diagnosis Using Dissolved Gas Analysis Data
Energies, 2018 Dissolved gas analysis (DGA) of the oil allows transformer fault diagnosis and status monitoring. Fuzzy c-means (FCM) clustering is an effective pattern recognition method, but exhibits poor clustering accuracy for dissolved gas data and usually fails to

Multiple incipient fault classification approach for enhancing the accuracy of dissolved gas analysis (DGA) [PDF]
IET Science, Measurement & Technology, 2019 Multiple incipient faults are practically known to exist in transformers. They tend to produce suddenly changing ratio limits in ratio‐based methods or oscillation of fault location in graphical methods. In consequence, the energy associated with them lies in‐between low and high severity single faults.

Influence of Oil Status on Membrane-Based Gas–Oil Separation in DGA
Sensors, 2022 Gas–oil separation by membrane stands for a promising technique in dissolved gas analysis (DGA). Since the accuracy of DGA relies on the results of gas–oil separation to a great extent, it is necessary to study the influence factor of membrane for better
